Reader's Block?

Is there such a thing?

I am currently half way through Winston Churchill's biography (the Jenkins one) and seem to have stalled at the start of the second world war.

I'm also half way through the latest Peter Hitchens book, A brief history of crime and seem to be stalled at the start of the gun bit.

These are the parts of the books I should find the most interesting but I just can't seem to get round to reading them.

So what do I go and do? I start a third book, Shadow Puppets by Orson Scott Card. I'm close to half way through now. Fingers crossed.
